Hi, I'm using XE 1.3 with xwiki-plugin-sql-1.3.jar. I put the jar in
WEB-INF\lib, append ua.gradsoft.xwikisql.SqlPlugin to xwiki.cfg and restart
Tomcat.
When I run XWiki, the following error is thrown:
*exception*
javax.servlet.ServletException: Servlet execution threw an exception
com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:117)
*root cause*

How to solve this problem? Any help would be high appreciated.
